62 check-ins using file src/pragma.c version 9e778dec

2011-06-06
14:51
Modify fts3rnd.test to run tests for both "ORDER BY docid ASC" and "ORDER BY docid DESC" with both order=ASC and order=DESC FTS tables. Fixes for some bugs found. (check-in: 89f2f482 user: dan tags: fts3-prefix-search)
06:55
Clean up the code for processing FTS4 options a bit. (check-in: 0425138a user: dan tags: fts3-prefix-search)
2011-06-04
20:13
Remove some unreachable code. (check-in: 650e1a79 user: dan tags: fts3-prefix-search)
20:04
Allow the "order=DESC" and "order=ASC" parameters in FTS4 "CREATE VIRTUAL TABLE" statements. Tables created with "order=DESC" store all doclists in descending order, which allows optimizations normally applied to "ORDER BY docid ASC" queries to be used with "ORDER BY docid DESC" queries instead. (check-in: f6a0193f user: dan tags: fts3-prefix-search)
2011-06-03
18:00
FTS changes: Remove unreachable code. Fix bugs. When processing a large doclist incrementally, read from disk incrementally too. (check-in: a4c7e282 user: dan tags: fts3-prefix-search)
12:15
Fix an #ifdef of SQLITE_OMIT_VIRTUALTABLE that had an extra "_" character. (check-in: 93e0be2b user: drh tags: trunk)
2011-06-02
19:57
Changes to improve performance and support LIMIT clauses on fts3 tables. This branch is unstable for now. (check-in: 28149a78 user: dan tags: fts3-prefix-search)
17:24
Fix a faulty assert() in the WAL-mode logic for read-only shared memory. (check-in: a13cfe61 user: drh tags: trunk)
15:48
Add a missing check for out-of-memory in the lemon code generator. (check-in: efb20b9d user: drh tags: trunk)
13:04
Merge the read-only shared memory branch into trunk. After this merge, an unprivileged process can open WAL-mode databases owned by another user as long as a database connection with write permission exists on the database file and if the readonly_shm=1 URI query parameter is supplied. (check-in: 19084a66 user: drh tags: trunk)
2011-06-01
20:13
Make use of the sqlite3GetBoolean() interface for more robust processing of the readonly_shm query parameter inside of unixShmMap(). (Closed-Leaf check-in: 1f930d7e user: drh tags: wal-readonly)
20:01
Simplify the wal-readonly branch so that it does not require changes to anything other than os_unix.c and wal.c and a couple of new error codes. (check-in: d6b4709d user: drh tags: wal-readonly)
19:44
Pull the latest trunk changes into the wal-readonly branch. (check-in: 0b63b713 user: drh tags: wal-readonly)
19:16
Avoid unnecessary duplication of SQL parameter names. (check-in: e704e869 user: drh tags: trunk)
18:15
Refactor the SQL parameter processing so that parameter names for values that are optimized out of the prepare statement are not forgotten. (check-in: b3aaf715 user: drh tags: trunk)
2011-05-31
17:08
Merge the latest trunk changes into the wal-readonly branch. (check-in: 2c6b5a28 user: drh tags: wal-readonly)
16:50
Fix a problem in the sqlite3TestErrorName() function (used only for testing) that appears to have originated from a bad merge. (check-in: a0ae314c user: drh tags: trunk)
11:56
Update the documentation to state that any parameter that is optimized out of a prepared statement becomes an anonymous parameter for which sqlite3_bind_parameter_name() returns NULL. (check-in: 701b8a23 user: drh tags: trunk)
2011-05-30
23:42
Minor performance improvements. (check-in: f9950c6a user: drh tags: trunk)
15:06
Update evidence marks on the URI filename tests to conform to the latest documentation. (check-in: 1bab03c4 user: drh tags: trunk)
14:35
Make sure the P5 argument to the OP_VUpdate opcode is always set to a valid conflict resolution code. (check-in: e3350dbd user: drh tags: trunk)
13:39

14:19
Changes to work with SQLITE_OMIT_VIRTUAL_TABLE. (check-in: 03f7d36a user: drh tags: trunk)
2011-05-25
23:18
Fix some minor and harmless compiler warnings. (check-in: a4755e70 user: drh tags: trunk)
20:25
Ignore malloc failures within the WAL file truncation attempt for journal_size_limit. (check-in: dd19105a user: drh tags: trunk)
19:17
If a prefix index of size N is not present, use a prefix index of size N+1 along with the terms index for queries for prefixes of length N. (check-in: cc83991c user: dan tags: fts3-prefix-search)
18:47
Merge trunk changes into experimental fts3-prefix-search branch. (check-in: f0f0a03d user: dan tags: fts3-prefix-search)

Fix a case where a malloc() error could lead to mismatched virtual-table xBegin/xCommit/xRollback callbacks. (check-in: d807304a user: dan tags: trunk)
18:34
Change fts4 so that the prefix= parameter is passes a comma-separated list of integers. For each integer N, a separate index of all prefixes of length N bytes is created. (check-in: be59bf49 user: dan tags: fts3-prefix-search)
15:54
Fix a compiler warning. (check-in: 6df99e52 user: drh tags: trunk)
01:16
Changes to savepoint in virtual tables for simpler and more consistent operation. (check-in: 92f26a8b user: drh tags: trunk)
2011-05-24
18:49
If the fts4 option prefix=1 is specified, have the fts4 module maintain an index of prefixes as well as terms. (check-in: b5bdc639 user: dan tags: fts3-prefix-search)
15:36
Do not invoke the xRollbackTo or xRelease methods of a virtual table without having first invoked an appropriate xSavepoint method. Add assert() statements to FTS3/4 to verify that this is happening in all cases. (check-in: 651ef242 user: drh tags: trunk)
00:35
Make sure the savepoint index is correct one calls to sqlite3VtabSavepoint with SAVEPOINT_BEGIN. (check-in: a9d09566 user: drh tags: trunk)
2011-05-23

02:48
Merge all the latest trunk changes into the sessions branch, especially the disappearing WAL transaction fix. (check-in: 5b1b536c user: drh tags: sessions)
01:21
When committing a WAL transaction, make sure at least one page is written to the WAL file so that the WAL subsystem will have a page on which to set the commit flag. Ticket [2d1a5c67dfc236]. (check-in: 67bf1c9a user: drh tags: trunk)
2011-05-18

03:02
Make sure the multiplexor shim uses a full pathname for temp file that it creates. (check-in: 186d7ff1 user: drh tags: trunk)

2011-05-06
18:34
Update comments and documentation associated with new URI parsing code. Add test file e_uri.test, containing tests mapped to documentation regarding URI filenames. (check-in: 92751788 user: dan tags: uri)
2011-05-05
18:53
Have the xFullpath method in os_win.c discard the initial "/" if a filename begins with "/X:", where X is any alphabetic character. Also fix some test issues in uri.test. (check-in: fe57a8f6 user: dan tags: uri)
12:35
